Investigation of Spatial Arrangement of Urban Parks and Presenting Their Optimal Model Using the VIKOR Model (Case Study: Regional Parks of Ardabil)

With the increase in population and the development of urbanization, humans have gradually shifted away from nature, and the excessive population density and interference in the natural environment and the creation of human environments have increased the human, environmental, physical and mental needs. On the other hand, the over-concentration of social, economic, and cultural activities in large cities has caused the population to flock to these cities, and as a result, the need for urban respiratory centers becomes more tangible. Therefore, the objectives of this research are analyzing the dismantling of urban green space (urban-regional parks) and providing an optimal model using multi-criteria decision-making rules (MCDM). The research method is applied, and in terms of its nature and method, is descriptive-analytic. The criteria are grouped into 9 components for the spatial layout of the urban-regional parks space. CRITIC techniques and paired comparisons are used to weigh the criteria used. Excel data analysis, GIS and SELVA IDRISI have been used to analyze the data and draw maps. In order to provide a suitable pattern for locating green spaces (Urban-urban parks) in Ardebil, VIKOR multi-criteria decision-making method was used. The results of the research showed that urban-regional parks in the east of area 1, southwest of area 3 and north of area 4 in terms of access to the park felt lack. Using the output map of the VIKOR model, suitable locations for the construction of new green spaces have been identified. Using the existing status map of the current green space and the output map resulting from the loading of the VIKOR method, an optimal model for the construction of the urban-regional park is proposed.
